Today I saw a lad with both ears pierced (the little flappy bit on the inside of the ear, rather than the normal lobe or up the top of the ear) and his spine... not sure how that works, but he had a bar through hs skin in line with his shoulders.

Another lad, seemed to have a pierced cheek... complete with diamond stud. I assume the same sort of appendage as a nose ring rather than an ear ring with a bit on the back!
